From residential apartments to high-traffic commercial buildings, Rainbow Locksmith NY installs, repairs, and replaces all types of door closers so your doors close smoothly, safely, and securely every time.
A door closer is one of the most hardworking hardware components in any building. It controls the speed and force at which a door swings shut, protecting your space from unwanted entry, maintaining fire safety compliance, and preventing costly damage to doors and frames.
At Rainbow Locksmith NY, our experienced technicians are equipped to handle all door closer needs — whether you're looking to install a new unit, repair a malfunctioning closer, or upgrade to a heavy-duty model for a high-traffic entry.
New installations for any door type — interior, exterior, residential, or commercial. We assess your door's weight, width, and usage frequency to recommend the right closer model and size for lasting performance.
From hydraulic fluid leaks to broken arms and misaligned brackets, our technicians diagnose and fix all door closer problems quickly. Most repairs are completed on the same visit.
When a door closer is beyond repair, we supply and install quality replacement units from leading manufacturers. We match the new hardware to your door's specifications for a clean, professional installation.
Is your door slamming shut or closing too slowly? We fine-tune the sweep speed, latching speed, and back-check resistance valves so your door closes with exactly the right force.
NYC building code requires fire doors to be self-closing at all times. We install and certify fire-rated door closers for stairwells, corridors, and service areas to keep your building compliant and occupants safe.
High-traffic offices, retail stores, and public buildings require heavy-duty closers that meet ADA opening force guidelines. We supply and install Grade 1 commercial closers that handle thousands of cycles.
No matter what type of door or closer you have, our licensed locksmiths have the tools and expertise to handle it.
The most common type, mounted on the top of the door or frame with a visible arm. Ideal for commercial and apartment entry doors. Available in multiple ANSI sizes (1–6) to match door width and traffic volume.
Hidden within the door or frame for a clean look, popular in upscale residential buildings, hotels, and modern offices. We install and service top-brand concealed closers including Dorma, LCN, and Norton models.
Installed in the floor beneath the door pivot point, ideal for frameless glass doors and heavy storefront entries. Our technicians handle precise floor-cutting and template positioning for a flush, professional finish.
Used when the closer arm must run parallel to the door, common in high-traffic corridors and push-side applications. Durable and vandal-resistant — a popular choice for schools, hospitals, and government buildings.
Need a door that stays open for deliveries or high foot traffic but still closes securely? We install and adjust hold-open and delayed-action models that give users extra time before automatic closing begins.
Connected to your building's fire alarm — the door stays open during normal operations and releases to close automatically when a fire alarm triggers. Ideal for corridors and stairwells in residential buildings and offices.
Ignoring a malfunctioning door closer can lead to security risks, code violations, and costly door or frame damage. If you notice any of the following, call Rainbow Locksmith NY today.
The closing speed is too fast, which can injure people and cause damage to the door frame over time.
The closer has lost hydraulic pressure or is incorrectly adjusted, leaving your space unsecured.
A worn-out spring or depleted cylinder means the closer can no longer hold the door shut against wind or pressure differences.
Dark, oily fluid near the closer body means internal seals have failed. The closer needs replacement before it stops working entirely.
The back-check or opening resistance is set too high, which may violate ADA requirements and is a safety issue for elderly and disabled users.
Physical damage to the arm compromises the closer's ability to function and control the door's movement safely.
